(WXIA) -- The Georgia Department of Transportation is reminding north Georgia residents to be mindful of temperature drops and to turn off their sprinkler systems.

GDOT released this statement Wednesday morning:

Every winter, we have icing issues due to automatically-timed sprinkler systems left on overnight in freezing temperatures. They can create a very hazardous condition for motorists the next morning.

Automatic sprinkler systems are often timed to operate at night, and when spray from the sprinkler is blown onto the road or water drains onto the road, black ice is formed, creating a hazard for motorists.

The Department urges residents and businesses to take a moment and ensure that automatic sprinkler systems are turned off. With sub-freezing termperatures on the way, motorists are cautioned to be on the lookout for icy patches or black ice, especially early in the morning.

(WXIA) -- Georgia Department of Transportation crews aren't letting the prospect of cold weekend weather deter them from working on road projects.

As usual, most of the work will take place overnight. However, a few projects will be completed during the day.

Work will continue along the Georgia 400/Interstate 85 interchange, which includes Cheshire Bridge Road, Sidney Marcus Boulevard and the Buford-Spring Connector. Lane closures can be expected during the day as well as at night.

One right southbound lane of the Buford-Spring Connector will be closed for bridge work daily from 9 p.m. to 5 a.m.

Sign work will take place on I-85 in both directions between Clairmont and Lenox roads. Two left lanes will be closed in both directions from 9 p.m. to 5 a.m.

A new project will take place on I-20 in both directions between Highway 5 and Liberty Road in Douglas County. Minimal delays are expected daily between 7 a.m. and 5 p.m.

ATLANTA -- Crews will continue working on the Georgia 400/Interstate 85 interchange in Atlanta this weekend.

Georgia Department of Transportation engineer Shun Pringle said one lane in each direction will be closed from 9:30 a.m. to 3 p.m. daily on Ga. 400 between I-85 and Peachtree Road. Drivers will also see delays on Cheshire Bridge Road, Sidney Marcus Boulevard and the Buford-Spring Connector.

But it all depends on the weather.

"With some rain expected on Saturday, I'm not sure how much (contractors) will be able to accomplish," Pringle said in a statement.

Sweeping, bridge and utility work, and drain cleaning will occur on I-20, I-75, I-85, I-285 and I-575 throughout the weekend. All projects will be completed overnight and will result in occasional closures.

ATLANTA -- The Georgia Department of Transportation has not scheduled much roadwork for this weekend.

Rain resulting from Tropical Storm Karen could move through metro Atlanta on Sunday and cancel any existing projects as well.

"We have single right lane closures planned for both directions on I-285 on the east side between Cascade and MLK and one on (Georgia) 400 southbound at Hammond Drive but the weather may change those plans," said GDOT Metro District Construction Engineer Shun Pringle.

Work will also continue on the I-85/Georgia 400 Interchange project, which could result in lane closures on Buford Highway, Sidney Marcus Boulevard, Cheshire Bridge Road and Lenox Road.
